Air Conditioner - St. Louis and Beyond
A complete system of heating, ventilation and air conditioning is known as HVAC. The purpose of an HVAC system is to provide cool air to your structure whenever the interior temperature exceeds a comfortable setting of your choosing. Central air conditioning, commonly referred to as central air or A/C, uses duct work to distribute cooled and/or dehumidified air to the rooms in your house or other building.
Most modern central air conditioner systems are known as split systems. In a typical split system, the condenser and compressor are located outdoors in a single unit. Inside the building, the evaporator is mounted in the air handling unit, typically your furnace. Sometimes there is a limited amount of space in which to work so the entire thing is packaged together in a single unit generally located outside the building on the ground or roof.
A central air conditioner system in a St. Louis home or business has several advantages over window air conditioners. When the central air system turns on, the air in the rooms is drawn in through return-air ducts back to the air handler unit. At the air handler (usually the furnace), air is pulled through the filter where airborne particles such as dust, pollen and lint are removed. Good filters can remove a significant amount of pollutants and we all know how much pollen is in the air on a Spring day in St. Louis. This can be very beneficial to those suffering with breathing problems such as asthma or other health related issues. The filtered air from the air conditioner is then routed back to the rooms through a separate set of ductwork. Since the central air unit is located outside the building, it generally offers a much lower level of noise on the interior of the building than a window air conditioning unit.
